` IMPROVEMENT IN VENTll...l-\`l'lNGk RAILWAY-CARS.

Specification forming part of Letters Patent No. 187,390, dated February 13, 1877 application iiled December 26, 1876.

To all whom it may concern Be it known that I, HENRY KING, of Allegheny, in the county of Allegheny and State y of Pennsylvania, have invented or discovered improved Ventilating apparatus fitted thereto.

Fig. 2 is a transverse sectional view of the front end of such car-body, showing the device for admitting indraft. Fig. 3 shows an enlarged vertical section of the apparatus for securing out-draft; and Fig. 4 is a top-plan view of such device, showing the register for regulating the draft.

It is a well-known fact that many gases deleterious to health, whether proceeding from respiration or other forms of combustion, are heavier than atmospheric air, and, consequently, are found at or near the bottom of rooms or apartments where they exist.

My invention relates to an improved ventilating device for securing the complete and perfect out-draftin cars having a floor-exhaust,

and also for more perfectly preventing iu-draft at the exhaust-opening.

This Ventilating device in the floor is constructed as follows: A pipe orflue, a, is placed in an opening in the oor, and supported therein by the shoulder or flange a', Fig. 3. Any desired form of register-gate e, Fig. et, is placed at the inner opening of this flue, on a suitable seat in the flange a', or on the spiderframe c, Fig.3. The one shown is the ordinary rotary register. To the part a is jointed, by a kind of swivel or socket connection, the elbowflue or vane b. A flange or socket, n, is made on the lower end of the piece a, of suitable size and form to receive the adjacent end of the vane b; A spider-frame, c', is placed at or near the base of the socket n, against the periphery of which the end of 1 axis.

the vane b may abut, if desired, and preferably a like spider-frame, c2, is placed in the adjacent end of the vane. The two parts'a and b are then connected by the rod d, which passes through the centers ot' the spiders c c1 c2, to the lower angle of the elbow or vane b, and by a nut, s, on the end of therod the two parts a and b may be held at the proper tension to permit the elbow or vane to turn freely in the socket n upon the rod d as an The nut s may be locked in any convenient way to prevent unscrewing. At or near the open end of the vane b I pivot a light buttery-valve, e, with its axis or pivotingpoints a little above the center, or more remote from the edge of the valve nearest the discharge or mouth of the flue, so that an outgoing current will open the valve and permit discharge by its excess of pressure on one side of the pivots or axis, and an ingoing current will, in like manner, close the valve. An. arm, g, is secured to the valve in such manner as to prevent the valve fromopening too far to perform its proper function. The vane b being free to turn, as de.

scribed, the action'of the outside air upon it when the car is running will cause the vane to turn its mouth or open end toward the rear, and the forward motion with the car will tend to create a vacuum in the flue, and when the register e is open, a corresponding current from the inside of the car to supply such vacuum. The tendency to form a vacuum in the ue, or at its mouth, will vary with the speed of the car, and the current from the car through the flue may be regulated at pleasure by the register e; This current from the car will carry out such gases as may have settled to the floor much more thoroughly than can be done by other systems of ventilation, and

screws o o, or other suitable Ventilating de vices7 open from the chamber A to the inside of the car, and supply fresh air as desired. Besides these end registers, others of any suitable kind may be placed alou'g the side of the car, near the top, in any desired number, and also the usual lues may be provided through the top, if so desired, for discharging heated air and other light gases.

I claim herein as my inventionl. A Ventilating device for car-doors, consisting of register e, barrel a, vane b, swiveled thereto by flange and socket-joint, spiders c c', rod d, and valve t, combined and arranged substantially as set forth.

2. In combination with the swinging vane b, the valve v and stop-arm g, arranged substantially as set forth.

In testimony whereof I have hereunto setx my hand.

HENRY KING. Witnesses:
